F30/E9X/E8X Big brake kit

The Ultimate OEM+ Big Brake Kit for BMW F3X, E9X & E8X

Unleash Your BMW's True Stopping Power.

Transform your BMW's braking with our modular Big Brake Kit for the F30, E9X, and E8X chassis. Replacing factory sliding calipers with a fixed 4-piston setup delivers shorter stopping distances, superior heat management, and a precise, immediate pedal feel—perfect for spirited driving and track days.

Key Features & Modular Design

• 4-Piston Fixed Calipers: Rigid, lightweight calipers ensure even pad wear, eliminate flex, and provide massive clamping force with consistent, fade-free performance.
• Custom Powder Coating (Upon Request): Calipers can be professionally powder coated in your choice of color for a durable, heat-resistant finish that matches your build.
• 340mm Brake Discs (Your Choice of Brand): Pair calipers with 340mm rotors from the brand you, drilled/slotted and upon trust—OEM-style or two-piece floating. The larger size adds thermal mass and brake torque.
• High-Performance Brake Pads (Street Applications Only): Choose from a range of street compound pads from your preferred brand. These pads offer excellent stopping power, low noise, and minimal dust for daily driving and spirited road use.
• Optional Brake Duct Kit: Channels cool air to the rotor center, reducing temperatures, fighting fade, and extending pad and rotor life.

Optimized for Your Chassis

• Master Cylinder Advantage: Best paired with the BMW Master Cylinder (Part #34 33 6 785 664). Its 25.4mm diameter is perfectly matched to the calipers' fluid needs, eliminating excess pedal travel.
• Wheel Fitment: Fits most 17-inch or larger wheels. (Spoke design and offset affect clearance; fitment template available on request.)
